abstract = "Due to its optical and electrical properties, low toxicity, chemical and physical stability, as
well as inexpensiveness, zinc oxide (ZnO) based materials have a great potential to be used
as photoelectrode in photo(electro)catalysis. Photo(electro)catalytic activity of ZnO materials
can be improved by modification of particles morphology and surface topology.
In this work, the influence of two different surfactants: cetyltrimethylammonium bromide
(CTAB) and Pluronic F-127, on the crystal structure, morphology, optical and
photo(electro)catalytic properties of ZnO particles, were examined. ZnO powders were
synthesized by microwave processing of a precipitate which was previously prepared by
"drop by drop" method in the presence of the surfactants. The crystal structure and phase
purity of the ZnO particles were determined by X-ray diffraction and Raman spectroscopy.
The effects of the surfactants on ZnO particles morphology were examined by the field
emission scanning electron microscopy (FE-SEM). The optical properties were studied using
UV-Vis diffuse reflectance and photoluminescence spectroscopy. Photocatalytic activity was
examined via decolorization of methylene blue under direct sunlight irradiation. It was found
that synthesized ZnO powders have a significant photocatalytic activity. Electrochemical
properties were studied using linear sweep voltammetry and impedance spectroscopy in
Na2SO4 electrolyte. ZnO powder synthesized in the presence of CTAB (ZnO/CTAB) showed
the most significant reduction of potential and the fastest kinetic of oxygen evolution.",
